Sports drinks have become a staple of American athletics. Lumaslim Review Every major sports team including the NFL, Major League Baseball, and NASCAR, are sponsored by and use sports drinks. Given the large amount of calories and sugar in the drinks, the issue is who needs them and do they quench thirst and really rehydrate people?
Physical activity of any kind exposes everyone to the possibility of dehydration. Numerous factors determine how one sweats and therefore how much water replacement will be needed during and after exercise. Fluid replacement depends on environmental factors including temperature, sun exposure, humidity, and wind, as well as the intensity and duration of the activity. Not only is there a difference between different activities, but between individuals; some people simply sweat more than others and need greater fluid replacement.
Excessive dehydration is as a loss of a body weight of 2% or greater with physical activities. Thus a 160 lb person is dehydrated if he loses 3.2 lb. or more during an event. They use average sweat rates (the amount of fluid lost per hour during exercise) to predict the possibility of dehydration. Here are some sports performed outside and the average sweat rates: basketball- 1.4 liters/hour, soccer -1.5 liters/hour, tennis -1.7 liters/hour and running 0.75 liters/ hour (at a speed of 5 mph.).
